QLAMP-SHAZDE-FRAME, CENTER minimum,

Original No.11,695,223, aaieaf This invention relates, to lamp-i shadeframes, and refers more particularly to an improved center element,constituting means for mounting lamp Sha de ,1 me on a pp rter holder. rl r present invention aims fortits; principalob1ect to prov de'an-lmproved center element for a lampshade frame which is adaptedtobeincorporated in and to become a substantially integral partthereofso that'a last- 1 "ing and rigid connection between the shade frame andcenter element is obtained, without resorting to welding or solderingprocesses.

. vThe invention more specifically contemplates a lamp shade framecenter element which is spun, stamped or otherwise formed from sheetmaterialto provide a hub definmg a central opening and a sectlonextending outwardly from said hub, which section The inventionfurthermore residesin theimproved means for anchoring the inner termlnalofeach arm or W1re between the outwardly extending section of the centerelement and the inwardly bent portion of, said section whereby toprevent radial displacement or relative movement between the element andarm in any direction.

Other objects reside the comparative simplicity of construction of thedevice, the economy with which the same may be produced and the generaleificiency derived therefrom. a 7

With the above recited and other obj ectsfin View, reference is had tothe following description and accompanying drawings, in which there isexhibited one example or embodiment of the invention, while the appended claims define the actual scope Z In the drawings Figure 1 is aperspective view of the center element connected to the arms of a lampshade frame.

Figure 2 is taken approximately on the line indicated at 2-2 in Figure1.

Referring to reference, A designates the armswhich project radiallyinward from a lamp shade frame, not shown,and B refers generally to thecenthereof.

= UNITED STATES ATEN' E the presentinventiom .which element is designedto serveas'a' means for mounting a lampshade frame on a suitable supportsuch asthe' threaded end of the shell of an electric lamp socket or anyother equivalent orholder, 1 v i The center element comprises a substan;tially cylindrical or tubular hub 10 having .an outwardly projectingannular flange or sec tion 11 atone of its ends,,,thesa idfiange orsection 11 having a portion 12 bent" inwardly into a positionsubstantially parallelto and underlying, the flange. The structure described is spun, stamped or otherwise formed from sheet material and isprovided at the uncture or connecting bight of the portion 12 with thesection or flange 11, with the circnmferentially spaced openings 13corresponding in number to the number of arms A. The hub 10 may beinternally threaded as at 15 to engage over the shell of an electricisprovided with means to form a projection 18 on the inner surface ofthe flan e portion 12 and at the same time to forma epression in eacharm terminal within which the projection 18 is received for the purposeof preventing radial outward movement of the arms. It thus follows thata centerelement has been devised which when incorporated in the shadeframe forms a substantially integral and rigid part thereof so that afirm and lasting connection between the centerelement and theframe isobtained; It, therefore, follows that when the shade is properly mountedon a support, relative movement between the shade frame "arms and thecenter element is precluded, and this withoutthe necessity of welding,soldering or employing similar means of establishing a connectionbetween the arms and the center element What is claimed is: s I a 1. Acenter element for mounting a lamp shade frame on a: support comprisinga substantially cylindrical hub, a radially project ing Ushaped portionhaving an apertured bight, a radial arm extending through the aperturedbight betweenthe leaves of the U- from one of the leaves recessed in theinner end of the arm for anchoring the same against radial outward andlateral relative movement with respect to the center element.

2. A center element for a lamp shade frame comprising a sheet metalmember having a substantially cylindrical hub, an outwardly projectingsection at one end thereof having an inwardly bent portion underlyingsaid section, said section and portion at their juncture having anopening through which the lamp shade frame arm extends radially inwardand means for anchoring the arm against radial outward and lateralmovements comprising a recess in said arm and an inward projection ofsaid portion engaging the recess of the arm.

3. A center element for a lamp shade frame comprising a hub defining acentral opening and a section extending outwardly from said hub, saidoutwardly extending section having an inwardly bent portion apertured atits juncture With the section for receiving and gripping a lamp shadeframe arm and an instruck projection from said inwardly bent portion,recessed in the inner end of the arm whereby said arm is anchoredagainst radial outward and lateral movements.

4. A center element for a lamp shade frame comprising an annular memberdefining a central opening and a portion bent inwardly from the outerperiphery of said annular member, said portion being formed with anaperture at the juncture thereof with the annular member for receivingtherethrough, the arm of the lamp shade, said inwardly bent portionhaving an in-st-ruck projection recessed in the inner end of the armwhereby said arm 1s anchored against radial outward I movement.
